GoodBed Expert Review
Our Take on Beautyrest Harmony Lux Diamond Ultra Plush Pillowtop

Founder of GoodBed
Michael Magnuson

Founder of GoodBed, Leading Mattress Expert

Bottom Line - Here was our assessment of this product.
Bottom line best icon BEST if you
  • Want a soft mattress
  • Are either a side or back sleeper
  • Are easily disturbed by other movements in the bed (motion isolation is excellent)
  • Have a clear preference for being hugged or cradled by your mattress
  • Prefer a slightly above average amount of 'memory feel'
  • Like a little bounce in your mattress, but not much
Bottom line not ideal icon NOT IDEAL if you
  • Are a stomach sleeper
  • Have a strong tendency to sleep hot (temperature regulation is pretty good, but not the best)
  • Frequently sit or sleep along the edge of your bed (edge support isn't the best, but is still pretty good)
  • Tend to have difficulty changing positions during the night (though ease of repositioning is still pretty good)
  • Want a natural or organic mattress (though this mattress is still OK in terms of avoiding harmful chemicals)
